PICKET SHARPENER AND SHAPER.

Specification of Letters Patent. Application filed December 1, 1913.

Patented Aug. 25, 1914. Serial No. 804,021.

To all whom it may concern Be it known that I, WILLIAM O. HAM- uoxn, a citizen of the 7 l of Canada, have invented a new and useful Picket Sharpener and Shaper, of which the following is a specification.

picket sharpener and shaper, and aims to provide a novel and improved device of that character.

date various widths and thicknesses of pickets, and in order that the pickets may be sharpened or shaped as desired.

It is also within the spirit of the present invention, to provide an appliance of the character specified, which will be comparatively simple, durable and inexpensive in construction, as well as simple, convenient, practical and eflicient in its use.

With the foregoing and other objects in. view which will appear as the description of the invention proceeds, the invention resides in the combination and be made within the scope of what is claimed without departing from invention.

The invention has been illustrated in its preferred embodiment in the accompanying drawings, wherein Figure 1 is a side elevation of a j ointer or table, the top of which is provided with a transverse opening 2 in which the cutter 3 works, the cutter 3 being mounted on a retary shaft 4 driven by belt power, or the like. The cutter 3 has its blades so arranged,

through the opening 2, slightly above the plane or face of the top of the jointer or table frame.

The present attachment embodies a base plate 5, disposed upon the top of the jointer or planing table adjoining the opening 2, and equipped along one edge, with a longitudinal upstanding flange b. The base plate 5 is adjustable longitudinally upon the jointer frame, to and from th 4, and to this end, the base plate 5 is pro the base plate 5 any position to which it is slid. That end of the flange 6, adjoining the opening 2, or the forward end of the flange, is provided with an upright portion or standard 6 having a slot 10 above the cutter 3.

A carrier plate 11 is dis-posed snugly against the outer at its forward end has a shouldered clamping bolt 12 whicl 1 engages thcrethrough, and passing through the slot 10 of the standard 6. The bolt or fulcrum member 12 is adapted to pivot the carrier plate 11 to the standard, and when loosened, is adapted to permit the carrier plate 11 to be adjusted vertically. e carrier plate 11 extends away from the opening 2 and is provided along its lower a flange or ledge 13 adapted to rest upon jointer frame, and serving for the picket 1 1, the picket 14 being placed on edge on the flange or ledge 13 and resting atly against the carrier plate 11.

t the outer or rear end, the carrier plate 11 supports a plate 15, a clamping bolt 16 being engaged to the plate 15 and passing through a longitudinal slot 17 in the rear end portion of the carrier plate 11, and a thumb or clamping nut 18 being engaged 011 the bolt 16 to clamp the plate 15 at any adjusted position. The plate 15 is provided at its forward end with a flange 19 servln as a seat or rest articles. The present attachment is comparatively simple, and may be readily applied to an ordinary jointer or planing table, or to any other suitable mechanism embodying a convenient cutter.

lVith the present appliance, the pickets may be readily applied to the same, and operated upon, and then removed, the entire operation being carried out in a simple and expeditious manner.

Having thus described the what is claimed as new is:

1. The combination with a table having an opening, and a cutter working within the opening, of an attachment comprising a base plate mounted on the table adjoining the opening, a fulcrum member carried by the base plate above the cutter, a carrier fulcrumed to the fulcrum member and extending away from the said opening, and means carried by the carrier for holding a picket with its end protruding above the cutter for engagement therewith when the carrier is swung away from the table.

2. The combination with a table having an opening, and a cutter working within the said opening,

As a means for holding the picket 11 upon the flange or ledge 13, an eccentric 21 is pivoted to the carrier plate 11 intermediate its ends, and is provided with a handle or lever 22 projecting rearwa'rdly. The handle or lever 22 carries a supplemental or auxiliary holding means, embodying a vertical slotted strip 23, and a clamping screw 2 1 engaged through the slot thereof and taking into the handle or lever 22, the lower end of the strip 23 being bent angularly to form a foot 25 adapted to rest upon the upper edge of the picket.

In the operation of the sharpener and shapcr attachment, the picket 1a is placed on edge upon the flange or ledge 18, flatly against the carrier 11, and the end rest 15 is adj usted properly along the rear end portion of the carrier 11, according to the length of the picket. After the picket is thus positioned, the handle 22 is depressed, whereby the eccentric 21 clamps the picket upon the ledge 13, or if the picket is unusually narrow, the holder may be let down and clamped. by means of the set screw 21, so that the foot 25 and holder 23 engages the upper edge of the picket to hold the picket in place. The forward end of the picket projects over the rotary cutter 3, as clearly seen in Fig. 1, the carrier 11 and flange 6 terminating short of the cutter. After the picket has thus been applied to the carrier 11, the handles 20 and 22 are grasped by the operator, and the carrier 11 is swung upwardly, as indi cated by the dotted lines in Fig. 1, which will cause the forward end of the picket to be swung downwardly into engagement with the cutter 3, the carrier 11 swinging about the bolt 12 as a center or fulcrum. Thus, the lower edge portion of the forward eX- tremity of the picket is cut away upon a curved line or arc, as indicated in dotted lines in Fig. 1. The carrier 11 is then swung against the j ointer frame top, and the picket is reversed, in order that the forward portion of the other edge of the picket may be rounded as above described to complete the sharpening of the picket.

From the foregoing it will be apparent that the present device will accommodate pickets of various lengths, thicknesses and widths. Attention is also directed to the fact that the base plate 5 may be adjusted longitudinally to and from the shaft a of the cutter, whereby the end of the picket may be sharpened or shaped in various manners, and furthermore, the fulcrum or pivot bolt 12 may be adjusted vertically for variance in the cutting of the end of the picket.

The present device may not only be employed for sharpening and shaping pickets, but may be employed for sharpening or shaping sprags, stakes, and other wooden invention,

of an attachment comprising a base plate adjustably mounted upon the table to move to and from the said opening, the base plate having a standard above the cutter, a fulcrum member vertically adjustable along the standard, a carrier fulcrumed to the fulcrum member and extending away from the said opening, and means carried by the carrier for holding a picket with its end protruding above the cutter, whereby the end of the picket will engage the cutter when the carrier is swung upwardly away from the table.

8. The combination with a table having an opening, and a cutter working within the opening, of an attachment comprising a base plate mounted upon the table adjoining the said opening, and having a longitudinal upstanding flange, a fulcrum member carried by one end of the said flange above the cut ter, a carrier plate disposed adjacent the said flange, one end of the carrier plate being fulcrumed to the said fulcrum member, and the carrier plate extending away from the said opening, the carrier plate having a lower ledge forming a picket rest, and clamping means carried by the carrier plate thereon with one end of the picket pro ecting over the cutter.

In testimony that 1 claim the foregoing as my own, 1 have hereto affixed my signature in the presence of two witnesses.
